# Crisp Black Shadow

## Essence

Hard black shadow for high-contrast affordances.

## Token

- `--shadow-crisp-black`

## Visual Role

Crisp offset shadow that gives white labels and white icons a sharper readable edge without turning into soft elevation.

## Use When

- Rendering inverse title and summary text over visual use-case tiles.
- Rendering the white diagonal arrow affordance inside `Use Case Card` gallery tiles.

## Do Not Use When

- A card needs soft surface elevation; use `--shadow-soft`.
- The element needs focus feedback; use Interaction States and keep this token as an additional layer only when needed.
